Simond MT500 Review: Affordable Camping Mattress for Festivals & Backpacking (2026)

The Simond MT500 XL trekking mattress is a game-changer for budget-conscious campers and festival-goers. At just £49.99, it offers a level of comfort and packability that rivals more expensive options. But is it worth the hype? I put it to the test, and here's what I found.

A Bargain Buy

What makes the MT500 stand out is its incredible value for money. For less than the price of a premium sleeping pad, you get a lightweight, compact, and comfortable mattress. The XL version, which I tested, provides a generous 195cm x 60cm of space, perfect for taller campers or those who like to sprawl. The fact that it costs under £50 is a steal, especially considering the quality and performance it delivers.

Comfort and Durability

The mattress's comfort is impressive, especially for its price point. The lengthways air chambers provide a surprising amount of cushioning, effectively absorbing pressure from rocks and uneven ground. I found it comfortable to sleep on my back and side, and the silicone patches on the upper surface help keep sleeping bags in place. However, it's worth noting that the mattress doesn't lie flat unless you add a sleeping bag and pillow, and you can feel the grooves of the air chambers, although this is barely noticeable once you're in your bag.

Durability is also a strong suit. The MT500 passed my durability tests with flying colors, showing resistance to jumping, dropping, and scraping. The self-adhesive repair patch is a handy feature, and the two-year warranty from Decathlon provides peace of mind.

Packability and Ease of Use

One of the MT500's standout features is its packability. Rolled up, it takes up about the same space as a 1-liter water bottle, making it incredibly easy to carry in a rucksack. Inflation is straightforward, taking less than a minute by mouth, and deflation is equally simple. The mattress is also lightweight, weighing just 600g, which is a significant advantage for backpackers and festival-goers.

Sustainability Considerations

While the MT500 is made from synthetic materials, which are not easily recyclable, its lightweight design and long-lasting quality make it a more sustainable choice. Regular use for several seasons can improve its sustainability profile, and the fact that it packs down small may also reduce transport emissions per unit shipped.

The Bottom Line

The Simond MT500 XL is an excellent choice for those seeking a budget-friendly, comfortable, and packable camping mattress. It's perfect for summer camping, festivals, and backpacking trips, offering a great blend of value and performance. However, for colder nights or those seeking a more luxurious experience, you might want to consider pricier options. But at this price, the MT500 is hard to beat. Personally, I think it's a fantastic option for anyone looking to enhance their camping adventures without breaking the bank. What makes this particularly fascinating is how it challenges the notion that you need to spend a fortune for a good night's sleep outdoors. In my opinion, it's a must-have for any camping enthusiast.
